The answer to the first question is that happens when the people joining don't have the mods you have active. I would guess since the GRPA mod was just updated to version 3.1, most people when they try to join your game probably have version 3.0. This would cause people to join and disconnect.

For the second question, are you trying to play a mission on the GRPA maps? None of the GRPA maps have a mission on them, so the maps will not show up in single player mission or in multiplayer coop mission. Most or all of the maps do have firefight on them, so you can play single player or multiplayer coop firefight on the GRPA maps.
